Awesome program first of all, I love it!
There are a few things I'd ask, if possible. First of all, let's say I have a directory, called music, that has 80 GB of music. However, there might be an occasional .txt file, a .jpg file, or something that is not music in the top directory. If that "song" is chosen, it crashes Audiosurf. Would it be possible to have the program automatically exclude, os simply ignore Album Art, or any other files that are not specifically supported to avoid that, and also so I can avoid going into 300 directories individually, and then manually adding all the song files, excluding the non-supported ones?
In addition, it would be really convenient, if we could add files/folders to the playlist, simply by dragging them and dropping them into Super Playlist Surf from Windows Explorer. If either of these are possible, please let me know.
